Essentially, the ketogenic diet promotes a "pseudofasted" state.3 After three to four days of fasting or following a very low-carbohydrate diet, the body, deprived of dietary sugar and starch, reduces insulin secretion and switches to primarily burning fat for fuel. The resulting overproduction of acetyl-CoA leads to formation of ketones—beta-hydroxybutyric acid and acetone—in a process known as ketogenesis.2,4 Whereas the brain can't use fatty acids for fuel, ketones can cross the blood-brain barrier, providing fuel to the typically glucose-hungry brain as well as to other tissues.
